1 Jul 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) departed Holy Loch for Malta. She made the passage together with HMS Visigoth (Lt. J.R.H. Haddow, DSC, RN) in convoy OS.82 / KMS.56.
No log is available for this period so unfortunately no map can be displayed. (5)

29 Aug 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) departed Trincomalee for her 2nd war patrol (1st in the Far East). She was ordered to patrol off the West coast of Siam off the Mergui Archipaligo.

For the daily and attack positions of HMS Stygian during this patrol see the map below.

6 Sep 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank a sailing vessel with demolition charges of the west coast of Burma in position 14°43'N, 97°44'E.

(All times are zone 6.5)
1505 hours - Sighted a schooner type vessel, she looked a modern vessel. Two coloured men were sighted on board.

1555 hours - Surfaced and fired a warning round across the schooners bows. The sails were immediately lowered. A boarding party was put on board and these brought back two English speaking natives. The schooner was then destroyed with demolition charges. The crew had turned out to be not two but seven. Four were sent away in the schooners small boat, the other three remained on board Stygian. (4)

17 Oct 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank three small vessels with gunfire near the mouth of the Bernam river.

(All times are zone -6.5
0600 hours - Surfaced in position 03°39'N, 100°46'E and boarded a junk. The junk was found to be under Japanese control. The cargo was oil drums amongst other general cargo. Sank the junk by a demolition charge.

0625 hours - Sighted a coaster bearing 010°, range 5 nautical miles. Enemy course was 130°, speed 8 knots. The target was about 130 feet long and of about 350 tons. Opened fire with the deck gun. It sank in position 03°45'N, 100°49'E after 37 rounds.

Then a large junk of about 100 tons was sighted close inshore. Closed and then opened fire. 20 Rounds were fired. By now the target was beached. The range was 4000 yards and could not be closed. to destroy this junk a lot of 3" ammo would be needed. Left the area for deeper water.

0718 hours - Sighted a small vessel with a very tall mast bearing 310°. When the range was about 5 nautical miles this ship was seen to be a small submarine chaser. Turned away to the Southward and increased to full speed.

0819 hours - The target sank in position 03°56'N, 100°40'E. 28 Rounds were expended. While withdrawing to deeper water a large three-masted junk was sighted. She was anchored and was engaged with the gun from 2800 yards. 20 Rounds were fired for about 10 hits. A fire was started but this was later observed to have died down. When last seen she was still floating and showing no signs of sinking.

0830 hours - Dived for an aircraft which remained in the area for some time.

0945 hours - Surfaced to board and destroy two junks. An aircraft forced Stygian to break off the action and dive. (4)

20 Oct 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank a large coaster and a small vessel with gunfire in the Malacca Strait. Several other vessels were damaged.

(All times are zone -6.5)
1339 hours - The Officer of the Watch reported an object moving up the coast. Closed at speed and made out a convoy of approximately a dozen small ships on a course of 320°, speed 8 knots. There were three small coasters of approximately 200 to 300 tons. These were followed by a large coaster or tanker of about 800 tons. They were surrounded by a collection of small craft. It was intended to torpedo the large coaster but when closing an Anti-torpedo boom was encountered preventing Stygian to close any further.

1409 hours - Surfaced for gun action. Before fire could be opened Stygian had to dive for an aircraft.

1424 hours - The aircraft disappeared over the land so surfaced again. Fire was now opened on the large coaster from 5000 yards but decreasing to 3500 yards at the end of the action.

1440 hours - After 81 rounds the ammuntion was expended. The coaster was ablaze from end to end. A motor boat or landing craft had disintegrated on being hit by a shell. Slight damage at least was suffered by most of the other vessels. Stygian now set course for deeper water.

1500 hours - The coaster was seen to sink in position 03°04'N, 99°56'E (4)

24 Oct 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) attacked a Japanese submarine with two torpedoes North of Sumatra. No hits were obtained on the target which was either RO-113 or RO-115 (offsite links).

(All times are zone -6.5)
1353 hours - In position 06°32'N, 96°42'E sighted an object through the persicope bearing 090°.

1355 hours - The target drew slowly to the left, dived.

1414 hours - Sighted a submarine, later identified as Japanese Ro 100-class. She was zig-zagging on a main course of 285°, speed 11 knots.

1443 hours - The target detected the periscope when about to open fire. She altered course to Port.

1447 hours - Fired two torpedoes from 1200 yards. These exploded shortly after firing and are thought to have prematured. The targets HE was however not picked up afterwards. (4)

(All times are zone -6.5)
1409 hours - Sighted an object moving down the coast, 8 nauticsl miles South of the mouth of the Bernam River.

1430 hours - Surfaced and identified the target as a Southbound coaster of about 200 tons, speed 8 knots. Opened fire from 6000 yards.

1450 hours - Ceased fire after firing 104 rounds. The target was hit several times but showed astonishingly little sign of damage. Range oould not be cloased further then 3000 yards. The target was in shallow water. Then a fire caught the cargo, most likely oil so then stood off to reach deeper water as the fire now would do the job.

1505 hours - The target exploded and sank. (4)

7 Dec 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank a coaster and landing craft with gunfire in the Malacca Strait. Also two small gunboats were damaged in the same action.

(All times are zone -6.5)
0926 hours - Sighted an object moving down the coast. Closed. It was not possible to intercept this target before it reached shallow water while closing dived.

0955 hours - Surfaced. Now sighted that the target was a 300 tons coaster that was in a convoy with two landing craft and two small gunboats.

1001 hours - The gunboats had now closed to 4000 yards and opened fire with a 12pdr gun and machine guns.

1005 hours - In position 02°55'N, 100°03'E opened fire with the 3" gun at the coaster from 5000 yards.

1021 hours - The coaster was now well on fire so shifted target to the nearest landing craft.

1022 hours - Sank the landing craft. Now the 3" gun shifted target to the gunboats. During the entire action these had been taken under fire with the Oerlikon and Vickers guns. They eventually had closed to 2000 yards but when damaged by the machine gun fire they retired, range was now 7000 yards.

1025 hours - Ceased fire as it was not possible to close the targets any further in these shallow waters. Retired from the scene to make off for deeper water. (4)

10 Dec 1944HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) attacked a convoy of coasters with six torpedoes off Ulee Lhoe, Sumatra, Netherlands East Indies. The result of this attack in not clear as Stygian went deep upon firing.

(All times are zone -6.5)
0532 hours - Dived 4 nautical miles South of Pulau Weh. Set course to close Ulee Lhoe anchorage.

1040 hours - Sighted a submarine chaser coming from Ulee Lhoe.

1118 hours - The chaser stopped 1000 yards from HMS Stygian. Possibly she went out as a convoy might be sailing shortly. Went deep.

1138 hours - Returned to periscope depth. Found the chaser only 400 yards on the Port quarter. Went deep again.

1150 hours - Heard HE decreasing.

1220 hours - Returned to periscope depth. Saw the chaser moving towards the shore where a convoy of five coasters was forming. The coasters were in two colums and were forming one line about 300 feet long.

1232 hours - Fired six torpedoes from 3700 to 4000 yards. Two torpedo explosions were heard but the result could not be observed as Stygian went deep after firing.

1245 hours - The first depth charge was dropped. No damage was done in this short and ineffective counter attack.

She gave assistance to her badly damaged sistership and sent a signal for help. At 1500 hours HMS Raider (Lt.Cdr. J.C. Cartwright, DSC, RN) arrived at the scene and one and a half hour later Stygian set course for her patrol area again. (4)

16 Jan 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank three Japanese vessels in the Malacca Strait off the mouth of the Bernam river near position 03°40'N, 100°45'E.

(All times are zone -6.5)
1417 hours - Destroyed a tongkang (no. 2115) of 100 tons by a demolition charge. Cargo was 120 tons of salt, 2 tons of fire brick and 20 tons of coke.

1430 hours - Dived for an aircraft.

1507 hours - Surfaced and destroyed a 40 tons junk with gunfire.

1553 hours - Destroyed a 20 tons junk (named Kim Keng Lee) by a demolition charge. As the junks skiff could only carry three out of the crew of six the other three were taken on board. At 1624 hours these were transferred to a sampan. (4)

17 Jan 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank the small Japanese tanker Nichinan Maru and later a sailing vessel in position 04°43'N, 100°28'E.

1545 hours - Destroyed a small 10 tons junk with a demolition charge. She was also bound for Port Dickson and her cargo was also rice.

1612 hours - Destroyed another 10 tons junk.
The crews of the last two junks were then transferred to a sampan. (4)

25 Jan 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) fired two torpedoes at a coaster moored at a pier at Ulee Lhoe, Sumatra, Netherlands East Indies. Both torpedoes missed due to malfunctions.

(All times are zone -6.5)
0540 hours - Dived and set course to investigate the Ulee Lhoe Anchorage.

0832 hours - Fired two torpedoes at a coaster (approx. 300 tons). The first torpedo ran 4 degrees to the right. The second torpedo commenced circling so went deep. Bottomed at 50 feet. Retired from the area shortly afterwards. (4)

19 Mar 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) made a short stop at Exmouth Gulf for fuel and provisions, or they thought so. A signal had been sent to Stygian that she was to proceed to Onslow for fuel and provisions. However on board Stygian the signal was read as proceed 'on slow' for fuel and provisions.

(All times are zone -8)
0535 hours - Sighted a small vessel silhouetted against the dawn, the target appeared to be stopped.

0544 hours - Dived and closed to investigate. Soon after the target was identified as a sea truck of 200 tons. One machine gun was visible on the bridge.

0806 hours - Surfaced up sun in position 07°28'S, 115°04'E and opened fire.

0808 hours - Checked fire as the crew were abandoning ship and putting up no fight. The target was already ablaze and settling.

0810 to 0845 hours - Picked up 10 of 11 survivors seen in the water. The 11th swam away twice and was not seen later.

0935 hours - One of the Javanese survivors had died and was buried at sea. He was the 2nd engineer of the sea truck. While in the water he had a large chunk of his side bitten out by a shark. The survivors / prisoners stated that there had been 22 men aboard the sea truck of which 4 were Japanese. They had broken down with engine trouble. The master, chief engineer, two Japanese and two Javanese had taken off in their boat to look for assistance and spare parts. Casualties were 2 Japanese and 4 Javanaese including the already mentioned 2nd engineer. As there was not enough room aboard the submarine and it was still quite early in the patrol all survivors were put on board fishing vessels that evening. (4)

27 Mar 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) torpedoed and damaged the Japanese minelayer Wakataka (1608 tons, built 1941, offsite link).
Her bow was blown off by the torpedo.

(All times are zone -8)
0542 hours - While in position 07°09'S, 115°21'E sighted an object bearing 076°. Dived and started an attack. The object was later identified as a large Japanese minelayer.

0610 hours - Fired the stern tube from 600 yards. Went deep on firing. Soon after the torpedo was heard to hit. HE and asdic transmissions ceased.

0625 hours - HE started up again and passed down the Port side dropping 5 depth charges. After a while HE faded out to the North-East when suddenly it stopped.

0715 hours - Returned to periscope depth to find the target bearing 060° at a range of 10000 yards. She was proceeding very slowly towards an anchorage. It was seen she was down by the bows. An enemy aircraft was seen patrolling overhead in due to the flat calm conditions had to go deep again to avoid detection from the air. (4)

29 Mar 1945In the early morning hours HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) detected by a Japanese escort vessel (possibly fitted with radar) while trying to attack an enemy convoy on the surface. Stygian is shelled and forced to dive. She is then attacked with 14 depth charges but these did no damage. (4)

2 Apr 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sank a Japanese coaster with gunfire in the Java Sea south of Kangean Island in position 07°02'S, 115°32'E.

(All times are zone -9)
0602 hours - Resighted the coaster that was spotted yesterday. It was a steel coaster of about 300 tons flying the Japanese naval ensign.

0646 hours - Dived to close the target and wait for better light.

0814 hours - Surfaced in position 07°02'S, 115°32'E and opened fire from 1700 yards.

0826 hours - Ceased fire.

0832 hours - Coaster number 447 (or 744 ?) was seen to sink. 54 Rounds of 3" and 200 rounds of Oerlikon had been used. Left the area on the surface at 12 knots. (4)

8 Apr 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) attacked two Japanese 'torpedo boats' about 25 nautical miles North of Madura Island, Netherlands East Indies. The ships attacked were most likely the Japanese torpedo boat Kari and Japanese minesweeper W-34. They were returning to Surabaya with the survivors from light cruiser Isuzu (all offsite links).

(All times are zone -9)
1053 hours - Dived for two aircraft that remained patrolling in the area. Decided to remain in the area and to wait and see what was the object of this unusual activity.

1329 hours - Called to the periscope by the Officer of the Watch. He had sighted what are thought to be two Japanese torpedo boats. The sighting was unfortunately rather late and Stygian was not in the best position to attack. Started an attack non the less.

1336 hours - In position 06°31'S, 113°10'E fired five torpedoes at the nearest target from 2000 yards. She was in line with the vessel that was further away. Stygian went deep upon firing. Four torpedo explosions were heard and there was hope for a double kill.

1341 hours - Five depth charges were dropped.

1356 hours - Returned to periscope depth. Unfortunately both targets were still in sight, one appeared to be undamaged the other was enveloped in thick black smoke. (4)

1540 hours - Identified the target as a small Westbound coaster. Closed further.

1624 hours - Surfaced in position 06°22'S, 110°48'E and continued closing. Opened fire when the range was 5000 yards on the nearest coaster (by now two coasters of about 200 tons were in sight). The first coaster soon sank. Fire was then shifted to the second coaster but although riddled with shells from 1800 yards she refused to go down. As Stygian was now in very shallow water on the surface for quite some time decided to make for deeper water.

In the same action Stygian also sank the Japanese auxiliary minesweeper Wa 104 (175 tons, former Dutch Djember) and destroyed the Japanese auxiliary submarine chaser Cha 104.

(All times are zone -9)
1423 hours - Sighted a coaster of about 400 tons making for Beuleleng from the West. Closed submerged.

1528 hours - Surfaced for gun action. Sighted not one but three coasters (200, 300 and 400 tons), a small tug and an auxiliary submarine chaser of the pier. All were heavily camouflaged.

1528 hours - Opened fire on the submarine chaser.

1531 hours - The submarine chaser slipped and opened fire on Stygian.

1540 hours - The submarine chaser now was heavily damaged. She ceased fire and was on fire forward. She beached herself and apart from a few bursts of 20mm machine gun fire would take no further part in the battle.

Fire was now shifted to the coasters at a range of 2000 yards. As there would not be enough ammunition to sink all with gunfire two torpedoes were fired. The first torpedo was set to 4 feet failed to explode. The second torpedo was set to 2 feet and it hit the 200 tons coaster which disintergated and it also broke the back of the 300 tons coaster which sank about 8 feet on to the bottom.

Meanwhile the 400 tons coaster was sunk with the 3" gun. The submarine chaser seemed repairable so a third torpedo was fired at it which blew the stern off.

The 400 tons coaster who had sunk had her bridge and upper deck awash and also seemed repairable. A fourth torpedo was fired at it to destroy it but this torpedo had a gyro failure.

1604 hours - Stygian immediately crash dived to 80 feet to avoid being hit by her own torpedo.

1615 hours - Returned to periscope depth. Saw two escort vessel approaching from the East. Went deep again to avoid. Only two distant depth charges followed. (4)

16 Apr 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) made a stop at Exmouth Gulf for fuel and provisions. At Exmouth Gulf she grounded but was refloated after three hours. She departed for Fremantle the same day. (4)

19 Apr 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) ended her 6th war patrol (5th in the Far East and 1st in the South-West Pacific area) at Fremantle. (4)

29 May 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) departed Subic Bay for her 7th war patrol (6th in the Far East and 2nd in the South-West Pacific area). She was ordered to patrol in the South China Sea.

For the daily and attack positions of HMS Stygian during this patrol see the map below.

31 May 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) and HMS Spark (Lt. D.G. Kent, RN) together bombard Storm Island in the South China Sea. They also land a raiding party. The island was however found to be uninhabited.
(4)

3 Jun 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) was ordered to take up a patrol position of the Lingga Anchorage to give cover for the allied landings in Northern Borneo. (4)

5 Jun 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) was ordered to patrol between the Northern end of Banka Strait and Lingga. (4)

6 Jun 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) was ordered to patrol off the Northern entrance to Banka Strait to intercept a Japanese Ashigara-class heavy cruiser that was reported by US submarines. (4)

7 Jun 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) sighted HMS Trenchant (Cdr. A.R. Hezlet, DSO, DSC, RN). A conference was held and it was decided that Stygian would patrol to the North of Hendrik Klippen Shoal and Trenchant to the South of it. (4)

(All times are zone -9)
0439 hours - When in a position 10 nautical miles North of the entrance to Banka Strait sighted starshell to the Southward. Soon after received a signal from HMS Trenchant that she had been detected by a destroyer. Altered course to assist her. When Stygian could not hear depth charges or gunfire it was assumed that Trenchant was clear of the enemy and Stygian therefore remained North of Hendrik Klippen Shoal.

0536 hours - Heard faint HE.

0722 hours - Dived and remained North of Hendrik Klippen Shoal.

1015 hours - Sighted what was later identified as a destroyer of the Kamikaze-class. Also aircraft were seen patrolling the area. The destroyer passed close to the East of Stygian. A good look around showed no other target in the area so when the destroyer turned South it was decided to attack her.

1050 hours - In position 01°52'S, 104°58'E fired two torpedoes from 800 yards. Both torpedoes missed. The tracks were most likely seen as immediately after firing the second torpedo she was seen to be under full helm. The torpedoes are thought to have passed very close astern. A counter attack of 27 depth charges now followed. The first of these were close causing minor damage. She however never gained contact and the remainder of the depth charges became more and more distant.

1347 hours - Distant explosions were heard. These proved to be the work of Trenchant sinking the Japanese heavy cruiser. The destroyer by now was 4000 yards to the North-West and was now heading South. It appeared the Japanese thought that there was only one submarine and that if they could keep it down the cruiser could pass unmolested. (4)

14 Jun 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) damaged a 500 tons coaster off the Northern entrance to Banka Strait. As the range could not be closed due to shallow water and gunfire from shore batteries the action had to be broken off.

(All times are zone -9)
1140 hours - Sighted a 500 tons coaster. She was hugging the Sumatran coast and was Northbound. Range was 9000 yards. Closed the range submerged.

1214 hours - Surfaced in position 00°58'S, 104°55'E and opened fire. Stygian however grounded and the action had to be broken off as the range could not be closed to more than 8000 yards. Also shore batteries opened up fire on Stygian. One hit was obtained. (4)

27 Jun 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) ended her 7th war patrol (6th in the Far East and 2nd in the South-West Pacific area) at Subic Bay. (4)

26 Jul 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) arrived at Brunei Bay. There she takes midget submarine XE 1 in tow and departed for her 8th war patrol (7th in the Far East and 3rd in the South-West Pacific area). She is to tow XE 3 to Singapore where the midget submarine was to attack the Japanese heavy cruiser Takao (offsite link). This was part of 'Operation Struggle' (offsite link).

For the daily positions of HMS Stygian during this patrol see the map below.

XE 3 succeded to lay her explosive charges on the bottom near the Japanese heavy cruiser Takao (offsite link) and managed to make their escape.

The crew of XE 3 were awarded the Victoria Cross for this mission. (4)

1 Aug 1945At 0029 hours (zone -9) HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) made rendez-vous with midget submarine XE 3 in more or less the same position where she was released. At 0339 hours the operation crew is taken on board and the transit crew is placed on the midget submarine. Course is then set back to Brunei Bay with XE 3 in tow. (4)

4 Aug 1945HMS Stygian (Lt. G.S.C. Clarabut, DSO, RN) ended her 8th war patrol (7th in the Far East and 3rd in the South-West Pacific area) at Brunei Bay. (4)
